BOOSTER-MOTOR SUPPORT.

Application filed January 22, 1924.

To all 'LU/loin 71mg/ concern.'

lile it known that l, Hanni' M. Peil-inning a citizen oli' the United States, residing at St. Louis, Missouri, have invented a certain new and useful lm ilirovenient in llooster-lvlotor Supports, ol wliielithe following is a speei lication, such as will enable others skilled in the art to which it apiiertain's to inake and use the saine.

My invention relates to railroad rolling` stock and consists in a new ineans tor mounting a booster inotor in a locoinotive.

Booster motors are usually carried upon the traine oli the truck, the axle ot which is connected to and driven by the booster lnotor. T he objects oft iny invention are to relieve the truck traine frein the weight of the inotor and to distribute the stresses due to the weight of the inotor to the locomotive Eranie and preferably in advance or the truck axle to which the booster inotor is connected.

In the preterred 'forni of iny invention illustrated in the accompanying di'anvings9 the booster inotor traine is in the forni of a cantilever inounted between its ents npon the axle of a trailer truck, carrying the booster inotor on the rear end and having its forward end engaging a member of the locomotive traine in front of the trailer truck axle.

In these drawingsllignre l is a top view of a radial trailer truck having;l iny improved booster inotor traine carried on the axle thereof.

Figure 2 is a loi'igitudinal vertical section 'through the booster' inotor traine and indicating portions of the trailer truck and the locomotive traine.

liienre 3 is a top view of the forward end ol' a non-radial trailer truck traine or locomotive traine ineinlier with the 'forward end ot the booster motor lil-arno applied thereto.

liigure 4 is a longitudinal. vertical section through the connection between the booster niotoi iframe and the locomotive 'lraine ineinbei.

liigures 5 and G .illustrate inodilications referred to below.

In the radial trailer truck construction indicated in Figures l and 2 the trailer truck traine is shown at l and the booster niotor frame at Q. The rear end of 'the booster inotor traine torina an engine bed 3 Serial No. 687,843.

ings through which the 'liinii'ie is carried on the truck axle T. At their iorward ends arins 5 are united to torni a central loconiotive 'traine bearing` tl? here shown as a concavo-eonves ineinber having` an upwardly facing spherical sui-lace 9 which engages a downwardly facing corresiiondingly shaped snil'ace 10 formed on the lower face of nien'iher ll on the locon'iotive liranie l2. The lower lace 13 ol ineinber 8 is also spherical in shape and lits a correspondingly shaped siirlaee 'lil provided on the ripper tace oll the lfornf'ard end l5 ol the trailer truck traine l.

The ineinbers 8, ll and lo are secured Vtogether by a bolt lo shouldered at lo, and lforin a common universal joint which perinits the booster inotor :traine and trailer truck `haine to swing independently of each other in a vertical plane and independently oll the locomotive traine. rlhe trailer truck and booster niotor traine can also swing in a horizontal plane independently el' the locomotive traine. rllie booster motor traine and trailer truck traine will nieve together in a horizontal plane as axle 7 will control such pivotal inovenient oic the booster' motor traine. Any relative inovein ent between the booster inotor liraine and truck traine due to any play between the niotor iii-aine bearings on axle l and between the truck journal box b iarii on the axle will be acconin'iodated by the ball and socket joint at the 'terward end oi the inotor and truck 'lran'ies ln the construction shown in Figures 3 and -l no radial truclf. traine is provided, the boost-er engine traine l? beingl secured at its forward end i8 to the locoinotivo traine ineinber ll by ineun's oli the ball and socket joint as shown in Figure fl. .lt will be understood that the booster Viframe 1T is carried upon the aide ot the trucx which supports the roar end oi' cradle 'lll and that the booster traino extends .rearwardly beyond this axle to carry Jilre booster engine similar to the arrangement shown in lfin'uio ln the construction shown in Figure 5 the booster liraine 20 and trnelr traine 2l, respectively, engage spherical seats and 23 provided on the locomotive traine cross iroin any elainpliip,` oi' the one by the other,

flo

lu Figure (i l show the truck iframe .e5 as seated against the locon'iot-ive cross brace 25 and the boostei frame 27 as straddling the inner end ot the truck frame and seated against the spherical lower tace 28 of the latter. This construction also eliminates a clamping or pinching action on the booster l'rame by the truck trame.

ln all ot these constructions the truck traine or the rear end ot' trie locon'iotive is ielieved ot the weight oit the booster motor which is carried on the truck axle by means ot' the cantilever motor trame and the stresses not taken care ol" by the axle are transmitted to the locomotive l'ranie 'l'orwardly o t the truck to which the booster motor is connected. Although secured to the main frame, directly or indirectly, the booster motor` trame may pivot tre/ely in every direction relatively thereto so that the motor can move with axle 'i' at all times.

Various other moditl ations in the details and construction of my device may be vmade without departing lron the spirit oll my ii'xvoution as expressed in the acconniauying` claims.

I claim:

l. in a locomotive, a main trame, a trailer abile having` pivotal movement relative to said frame, a horizontal member' secured near one end to said trame, supported intermediate its ends on said axle and pivoting` therewith, and booster motor carried by said member near its opposite end.

9. lu a loeou'iotive, a main frame, a trailer trucl; axle, and a booster motor traine secured to said main 'frame on one side oli said axle and carrying,r a booster motor on the other side of said axle.

In a locomotive, a main trame, a truck axle, and a booster motor lrame pivotally mounted intermediate its ends on said axle, carrying a booster motor at one end and pivotally connected to said main trame at its opposite end.
